Can we create a conscious agent by having two units: one rational and the other conscious?
Jürgen Schmidthuber has a similar concept of consciousness, maybe check out this article: 


  I would like to claim we had little, rudimentary, conscious learning systems for at least 25 years. Back then, already, I proposed rather general learning systems consisting of two modules.


There you also have one module that is occupied with decision making. The other module's job is to create a model of the world. 

Of course, a philosopher will tell you that we have no idea what consciousness is or "what it feels like to be ai with two units".
